It's a very nice place on a very convenient location near the BTS and terminal 21. Don't turn right in the evening though when coming out of the alley. There will be many prostitutes. Going left the area is very nice including many great restaurants, rooftop bars etc. In the neighborhood. We recommend the rooftop bar next door in the four point by Sheraton. Also the food at Chowpati is amazing (not very cosy but heaven for a foodie). My new favorite restaurant in Bangkok.
The room is nice and clean and had a great smell. Also Nong Dee is very kind and always ready to help. Value for money we didn't give the full amount of stars as on our first stay two weeks before our stay at Nong Dee we had a hotel that we realised was the same price as this beautiful Airbnb that we loved even a bit more as it included a very good breakfast and cleaning service. But if the prices for this particular hotel would go up we'd definitely be back with Nong Dee!
